Wema Water or Fuel Level Sensor 800 mm 12/24 V

Product description:

The Wema S3-A800 water or fuel level sensor with a length of 800 mm is a specialized resistive transducer designed for precise measurement of liquid levels in tanks, both water and fuel. The device is widely used in the marine, automotive, agricultural industries, and in specialized vehicles where reliable liquid level monitoring is crucial for safety and operational efficiency. The sensor is mounted vertically from the top of the tank by screwing it into a prepared mounting hole, ensuring tightness and installation stability. Thanks to the universal power supply voltage range of 12/24 V, the sensor is compatible with most onboard systems. The output signal in the form of variable resistance (240–30 Ohm) allows cooperation with a wide range of analog indicators, both factory-made and universal. The construction made of high-quality stainless steel guarantees resistance to corrosion and aggressive media such as fuels or seawater. The sensor features high measurement accuracy along the entire working length, and its design minimizes the risk of sticking and erroneous readings even in difficult operating conditions. The product complies with international safety and quality standards, confirming its suitability for professional applications.
